[TIMOB-12599] Android: label.toImage().width does not return correct width when Ti.UI.SIZE is assigned

Problem

Titanium documentation says that width property value of 'auto' has been deprecated and to use Ti.UI.SIZE. However, setting label.width to Ti.UI.SIZE causes label.toImage().width to always return value of 100. Setting the label.width to 'auto' always returns the correct width. This problem occurs on Android only and is not a problem on iOS so this is a parity issue.

Testcase

Run enclosed app.js file on Android emulator. This app will display two labels. Label one will be created with width:'auto' and label two will be created with width:Ti.UI.SIZE. The function .toImage() will be called to get the width of each label. The results will be displayed in the console. Expected Result <----- The width of label one using property width:'auto' is 145 -----> <----- The width of label two using property width:Ti.UI.Size is 145 ----->' Actual Result <----- The width of label one using property width:'auto' is 145 -----> <----- The width of label two using property width:Ti.UI.Size is 100 ----->' {panel:title=app.js}

var win1 = Titanium.UI.createWindow({  
    backgroundColor:'blue'
});

var label1 = Titanium.UI.createLabel({
	color:'yellow',
	top:100,
	text:'This is label one',
	width:'auto'
});

var label2 = Titanium.UI.createLabel({
	color:'red',
	top:200,
	text:'This is label two',
	width:Ti.UI.SIZE
});

win1.add(label1);
win1.add(label2);

win1.open();

Ti.API.info('<------- The width of label one using property width:\'auto\' is ' + label1.toImage().width + ' ------->');
Ti.API.info('<------- The width of label two using property width:Ti.UI.Size is ' + label2.toImage().width + ' ------->');
